[AMPS] Problem with SB-220 Bias Diodes

[Maurizio Panicara]

But someone told a number 30 wire 1/2 inch long fuse didn't blow up ......
Jokes apart, there's another issue often neglected that's what happens to a
GG tube when HV disappear and drive power stay on. Someone who opened tubes
could explain it better than anyone else.
